As you scale your idea, it is essential to measure your progress and evaluate your results. Knowing if your scaling strategy is working, and what metrics and indicators to use to track your performance and impact, are important steps for learning, improving, and adapting your idea to changing needs and expectations. Customer satisfaction, customer retention, customer acquisition, revenue, and impact are all metrics and indicators you should consider. Customer satisfaction can be measured by how happy customers are with your solution and how likely they are to recommend it to others. Customer retention can be measured by how many of your customers stay with you over time and how often they use your solution. Customer acquisition can be measured by how many new customers you attract and how much it costs to acquire them. Revenue can be tracked by how much money you generate from your solution compared to expenses and profits. Impact can be measured by the value you create for customers, society, and the environment.
